Definitions

  • the invention relates to a method for producing a bottle-shaped container by deep drawing, in that a film is clamped above a mold along an edge region which forms a container flange after being punched out, pre-shaped into a mold by deep drawing by means of a piston-like shaped body and then finished in this form by compressed air becomes. Furthermore, the invention relates to a deep-drawing mold for carrying out the method and to a deep-drawn bottle-shaped plastic container produced by the method and a container cap for the sealing connection with the container head of a container.
  • a method of the type mentioned is known from CH-A-352 279. This method illustrates that it has not hitherto been possible to produce the container jacket of a slim container corresponding to a bottle shape in one piece in a deep-drawing mold. For this purpose, two separately deep-drawn container parts had to be connected to each other along their flange surfaces in a third operation, so that the container jacket is interrupted by a circumferential flange.
  • BE-A-556 274 Since, in contrast to plastic containers manufactured in the blow molding process, deep drawing only allows a small depth of the container in relation to the diameter, BE-A-556 274 also proposed a bottle-shaped container made of two deep-drawn, shell-shaped halves to form so that it has a flange connection extending in the longitudinal direction of the bottle-shaped container. This has the disadvantage that it cannot be sealed with satisfactory reliability. In addition, the course of the flange connection to the bottom of the container requires that special structural measures must be taken there so that the container can assume a vertical position. The measure proposed by BE-A-556 274 to move the flange connection inwards in the bottom area has the disadvantage that the container halves have an undercut which makes their manufacture more difficult and prevents their space-saving, stacked storage and transport.
  • the invention has for its object to find a method of the type mentioned, which avoids the disadvantages of such known methods and which makes it possible to produce a stackable and thus quickly fillable, thin-walled and therefore very light bottle-shaped container with high working speed.
  • this object is achieved in that the preforming by means of the piston-like shaped body is carried out at least in two stages into a mold space tapering in the shape of a bottle in the direction of the deep-drawing movement, the preforming being carried out in the first stage by a molded body unit consisting of an enclosing and an enclosed molded body and in the second stage the preforming is continued by the previously enclosed molded body by moving it out to the lowest region of the bottle-shaped mold space from the enclosing molded body.
  • a deep-drawing mold is proposed, the mold space of which tapers in the shape of a bottle and the molded body unit carrying out the deep-drawing movement consists of an enclosing and an enclosed molded body, the enclosing molded body being piston-like on one tubular push rod is held, which encloses a push rod holding the enclosed molded body.
  • a filled, deep-drawn, bottle-shaped plastic container produced using the method according to the invention is characterized according to the invention in that the container jacket has a circumferential shoulder or a circumferential bead in the central part of its longitudinal extent, which subdivide it into a lower and an upper section, both of which are upward taper, the lower section being bounded at the bottom by a flange edge running transversely to the longitudinal axis of the container and the bottom of the container being welded to it.
  • the method according to the invention makes it easy to produce containers which have numerous advantageous properties.
  • the most significant advantage is that the container bodies can be transported stacked one inside the other from the manufacturer to the filler before the container bottom is welded on, so that a lot of transport and storage volume is saved.
  • the container body can be filled easily and quickly through its large bottom opening before the container bottom is welded on, so that the filling can be done in multiple lanes and no conventional bottle filling system has to be used.
  • the circumferential heel or bead contributes to the stiffness of the very thin-walled container body, just like the flange flange on the bottom.
  • longitudinal grooves or a paper sleeve connected to a jacket section can stiffen the container body. Its thin walls result in considerable material savings as well as the possibility of collapsing the container for waste disposal after use.
  • the stiffening paper sleeve which is preferably provided, can be removed beforehand by tearing off a built-in predetermined separation strip.
  • a container cap which can be sealed onto the container head is further proposed, which according to the invention is characterized in that there are incisions in the container cap which are opposite one another, so that they limit a closure flap which extends transversely over the container cap and which are suitable for the arrangement is determined above an emptying opening of the container, a deep-drawn sealing plug being located in the sealing flap and the sealing flap having a finger grip at its free end which extends away from the lower edge of the jacket part of the container cap and at least one hinge at its opposite end forming transverse groove is formed, which serves to pivot the locking tab between a closed position and a release position.
  • the basic structure of the deep-drawing mold 1 shown in FIGS. 1 to 3 without a thermoformed film is known per se, but what is new are the large axial length in relation to the diameter or the bottle shape of the mold space 2 and the molded body unit 3, in that it consists of an enclosing Shaped body 4 and an enclosed shaped body 5 there.
  • the molded body unit 3 is moved from the position according to FIG. 1 into the position according to FIG. 2 and thus up to approximately half the longitudinal dimension of the molding space 2, ie up to the line 13, so that the film passes through the enclosing molded body 4 accordingly is deep drawn.
  • the enclosed molded body 5 moves from the position according to FIG. 2 into the position according to FIG. 3 and thus out of the enclosing molded body 4 and takes over the further deep drawing into the lower region 15 of the molding space 2, so that a part of the film which previously lies against the end face 16 of the molded body unit 3 is deep-drawn.
  • the final shaping is carried out by compressed air, which flows from above past the molded body unit 3 into the preformed container body, so that the latter is pressed against the inner surface of the molded space 2 and assumes its shape.
  • the deep-drawn container body 11 is removed from the mold by moving the molded part 7 downward, so that the bottom part 20 of the deep-drawing mold forming the top wall 19 moves into the mold space 2 and ejects the container body 11.
  • a paper sleeve 21 was inserted into the deep-drawing mold before it was fed, the paper sleeve 21 being shaped and dimensioned such that it contacts the wall of the upper region 22 of the molding space 2 applies and comes in close, positive contact with the film forming the container body 11 during deep drawing molding under the pressure of the compressed air.
  • the shoulder-shaped shaping of the film resulting from the positive inclusion of the lower edge of the paper sleeve 21 preferably takes place where there is a circumferential groove 23 or shoulder at the transition between the upper and lower regions 22, 15 of the molding space 2 in the container body 11, which have been preformed by a shoulder 24 between the surrounding and enclosed molded bodies 4, 5.
  • the groove 23, which acts as a bulge on the outside, also contributes significantly to the stiffening of the very thin-walled container body 11, even if it does not correspond to the representations of FIGS. 6, 11, 14 and 16 is reinforced by a paper sleeve 21. Equipping the container body 11 with a paper sleeve is, however, also preferable for the aesthetic and advertising-effective design of a container according to the invention, since it can be easily printed.
  • the upper section 25 of the container casing which is smaller in diameter, can also be reinforced by a second paper sleeve, it is preferable to provide a wall profile in the upper section 25 of the container casing due to the preferably provided curvature 26 at the transition between the two frustoconical regions of the container casing contributes both to the reinforcement and to the advantageous aesthetic design of the container.
  • the wall profile consists, for example, of flat bulges 27 arranged next to one another in the circumferential direction at equal intervals in the circumferential direction, so that ribs 28 result between them, which reinforce the container jacket 11.
  • a circumferential stacking shoulder 29 is formed in their head area by the conical shape in the uppermost wall area 31 between the top wall 19 and the stacking shoulder 29 to the remaining area of the container casing.
  • the finished container 33 is only produced after filling the container body 11 by sealing or welding a slightly deep-drawn bottom wall 34 or a flat bottom wall 35 onto the flange edge 12 of the container body 11, the bottom wall being the large bottom side that faces upwards Fills opening 36 tightly. This would complete the container 33 if it is considered sufficient to leave the creation of a non-reclosable emptying opening to the end user, who cuts the container 33 open at any point for this purpose.
  • the opening of the container 33 is preferably facilitated by a closure device which enables a reclosure.
  • a closure device which enables a reclosure.
  • the sealing of the container cap 39 takes place along the edge bead 37 of the emptying opening 38 with less strength and moreover with a higher strength along a bead 40 which extends parallel to the edge of the cap and thereby encloses an area provided for the arrangement of a closure tab 41 on three sides.
  • two sealing tools are used, which, after the container cap 39 has been placed on it at different temperatures and different pressures, are briefly pressed on where the bead 37 or 40 in question runs below the flat cap wall there.
  • FIG. 16 An example of the formation of a sealing tool is shown in the upper part of FIG. 16. This serves to seal a second embodiment of a container cap 39 'or a closure system.
  • the cap region covering the emptying opening forms part of a closure flap 41 which, during the manufacture of the container cap 39, has been provided with a recess forming a sealing plug 42 by deep drawing.
  • the sealing plug 42 forms a well-sealing closure system with the edge bead 37 surrounding the emptying opening 38, this ensures that after the first opening by pulling up the closure flap 41 and peeling off along the sealing connection of the edge bead 37, a tight reclosure is possible.
  • the closure flap 41 is produced by introducing two mutually parallel cuts 44 and 45 into the thin-walled, deep-drawn container cap 39 in one operation using the two-part cutting tool according to FIG. 10. Before the container cap 39 is inserted into the lower part 46 of the cutting tool, it is punched out along its circumference after deep-drawing and along the contour of a laterally protruding finger grip 47 of the closure flap 41.
  • the cutting tool part 46 there is a receptacle 48 for the inclined arrangement of the container cap 39 and a recess 49 for the arrangement of its finger grip 47. Due to the inclined arrangement, with a cutting movement of the cutting stamp 50 in the container cap 40, the two, the closure flap 41 on opposite one another Side-defining incisions 44 and 45 are produced, which extend parallel to one another across the container cap 39 and into their jacket part 51 and end there at a short distance from the lower circumferential edge 52, so that there two short, non-cut wall parts 53, 54 of the container cap 40 remain, which are torn as the predetermined breaking connection when the locking tab 41 is torn open. Their integrity guarantees that the emptying opening 38 of the container 33 has not yet been opened.
  • a recess 56 is provided, the side walls are undercut 57,58 downwards, according to the indication by dashed lines, slightly so that the locking tab 41 after its bending back by 180 o latched there and when the container is emptied, for example by drinking, there can be no obstruction by the closure flap 41.
  • the bending back of the locking tab 41 into the locking position within the locking recess 56 is facilitated by at least one and preferably two or three closely spaced grooves 55 extending transversely to the locking tab 41 in that they form a hinge-like end region of the locking tab 41.
  • the resultant downward profiling of the closure flap 41 is received in a correspondingly large recess 59 in the top wall 19 of the container body 11, as the cross-sectional illustration in FIG. 7 illustrates.
  • the finger grip 47 has numerous wart-shaped depressions 60 which are produced during the deep-drawing of the container cap 39 and which serve for its grip.
  • a finger grip can, for example, also be designed in a ring shape with a larger punched-out area as a ring tab.
  • FIG. 14 and 15 show an embodiment of the container with a ventilation opening 61 which is arranged next to the emptying opening 38 and is provided inside the recess 59 of the top wall 19 of the container body 11. This prevents the creation of negative pressure in the container if liquid is discharged via the drain opening 38 e.g. is removed by drinking.
  • the sealing seam surrounding the emptying opening 38 continues around the recess 59, as shown in FIG. 15, in that an edge bead 62 is also formed there by an inner groove in the head wall 19.
  • FIGS. 16 and 17 show a container which differs from those of the exemplary embodiments according to FIGS. 4 to 15 by a different design of the head region and the closure device.
  • the head wall is cut out to such an extent that only an edge bead 63 remains, which surrounds a circular, relatively large emptying opening 64.
  • the closure is made by a Edge bead 63 sealed, deep-drawn piece of film 65 with laterally protruding finger grip 66.
  • the deep-drawn area of the piece of film is inserted into the emptying opening in the manner of a cover and lies sealingly against the inner surface 67 of the edge bead 63, so that a reclosure is possible after the sealing connection has been released .
  • the finger grip 66 is also slightly bendable, so that it bears against the container jacket when stacked one inside the other.
  • a container according to the invention which is produced in a bottle shape by deep drawing, can also be produced with other longitudinal and cross-sectional shapes of the container shell.
  • other longitudinal and cross-sectional shapes of the container shell For example, polygonal cross-sectional shapes with rounded corner areas are also possible.
  • Any deep-zisable film such as e.g. made of polyethylene, polypropylene, polystyrene. PET, among others, which can also be constructed in multiple layers.
  • the film deformed into a container for example, has a thickness of 1.7 mm before deep-drawing and is only about 0.6 mm thick in the flange edge after deep-drawing and only 0.2 mm in the container jacket.
  • an emptying opening 38 provided in the top wall 19 can also be closed by sealing a container cap that is deep-drawn from an aluminum foil.
  • the one-time opening is then carried out by removing the container cap by tearing it open along a predetermined dividing line and detaching it along the sealing connection.
  • the production of the container by deep drawing also enables them to be connected to a multiple pack in a simple, known manner.
  • 18/19 shows the connection to a pack of two as an exemplary embodiment, and the connection to a pack of four 71 is shown in FIG. 20/21.
  • Such a connection results from the fact that after deep-drawing the containers in a multiple form, they are not cut out concentrically along their flange edge 12, but along a common outer contour 72 or 73 and, in the case of a four-pack 71, additionally along a common inner contour 74, so that in each case between a connecting tab 75-79 remains in two adjacent containers.
  • a score line 80-84 which is pressed into each of the connecting tabs 75-79, forms a predetermined separating line, so that the consumer can separate a container from the pack 70 or 71.
